Economic analysis of swine injection technology

Catherine Trask
This dataset includes cost data gathered via interviews with swine producers in the Canadian provinces of Saskatchewan and Manitoba. Intensification of modern swine production has led to many new technologies, including needleless injectors. Although needleless injectors may increase productivity (by reducing injection time) and reduce needlestick injuries, the effect on risk for musculoskeletal disorders is not clear. This project will compare conventional needles with needleless injectors in terms of cost, productivity, injury rates, biomechanical exposures,...

Raw data and video outputs from a CE-QUAL-W2 hydrodynamic and nutrient model for different Lake Diefenbaker Reservoir withdrawal depth scenarios

Amir Sadeghian, Meghan Carr, Karl-Erich Lindenschmidt & Luis Morales-Marin
The Lake Diefenbaker CE-QUAL-W2 model has 87 horizontal segments starting at Saskatchewan highway 4 at the upstream extending to the Gardiner Dam and the Qu’Appelle Dam at downstream, and one-meter vertical layers with a maximum of 60 layers at the deepest point near the Gardiner Dam. Gardiner dam outflow is either via metalimnetic withdrawal through hydroelectric turbines or via a spillway during brief high flow periods. The current operational withdrawal depth of approximately 34m was...

Hydrological and meteorological dataset from the Lake O’Hara alpine hydrological observatory, 2004-2017

Jesse He & Masaki Hayashi
The Lake O’Hara watershed in the Canadian Rockies has been the site of several hydrological investigations. It has been instrumented to a degree uncommon for many alpine study watersheds. The following data are available in this dataset: Air temperature, relative humidity, wind, precipitation, radiation, and snow depth are measured at two meteorological stations near Lake O’Hara and in the higher elevation Opabin Plateau. Water levels at Lake O’Hara, Opabin Lake, and several stream gauging stations...

Fortress Mountain Snow Laboratory, Blowing Snow Camera Measurements, and Wind Velocity Data

Nikolas Aksamit & John Pomeroy
These data files include airborne blowing snow density measurements using a portable highspeed camera and 432 nm wavelength laser light plane apparatus. Blowing snow measurements were taken in the first 30 mm above the snow surface. Approx 30 cm away in the spanwise direction across the mean wind direction were two Campbell Scientific CSAT3 sonic anemometers situated on a single mast. The anemometers sampled raw measurements at 50 Hz. The height about snow for the...

Each file begins at midnight at the beginning of the recording day and runs until the end of the experiment, typically close to midnight. The two anemometers were...

Aggregate hydraulic conductivity data from site investigations in south-central Saskatchewan, Canada

David M. Ferris, Grant A.G. Ferguson & Gregory Potter
Pleistocene-aged glacial till aquitards are important shallow hydrogeological units across much of the Northern Hemisphere. Characterizing the hydrogeological properties of these aquitards at a regional scale is important for land use planning and resource management. Here, 606 hydraulic conductivity data points from 20 sites collected from 26 reports are compiled. The referencing information, spatial location, hydraulic conductivity test type, and any other information associated with the hydraulic conductivity data is included where possible. After filtering...

WETMETH: A new wetland methane model for implementation in Earth system models

Claude-Michel Nzotungicimpaye
WETMETH is a new wetland methane model developed for implementation in Earth system models. It is currently embedded in the frozen ground version of the University of Victoria Earth System Climate Model (UVic ESCM), an Earth system model of intermediate complexity (EMIC). Here we provide model output files with all variables analyzed in the model description manuscript. These model outputs include results from a historical run from 1850 to 2019 and sensitivity runs over the...

Hydrometeorological, glaciological and geospatial research data from the Peyto Glacier Research Basin in the Canadian Rockies

Dhiraj Pradhananga, John Pomeroy, Caroline Aubry-Wake, D. Scott Munro, Joseph Shea, Michael N. Demuth, Nammy Hang Kirat, Brian Menounos & Kriti Mukherjee
Hydrological, meteorological, glaciological, and geospatial data of the Peyto Glacier Research Basin (PGRB) in the Canadian Rockies are presented. Peyto Glacier has been of great interest to glaciological and hydrological research since the 1960s for the study of mass and water balance during the International Hydrological Decade (IHD, 1965-1974). Intensive studies of the glacier and observations of the glacier mass balance continued after the IHD, when the initial seasonal meteorological stations were discontinued, then restarted...

Model data for \"Irreversible ocean thermal expansion under carbon dioxide removal\"

Dana Ehlert & Kirsten Zickfeld
The related study uses a global climate model to explore the extent to which sea level rise due to thermal expansion of the ocean is reversible if the atmospheric concentration of carbon dioxide (CO2) declines. It is found that sea level continues to rise for several decades after atmospheric CO2 starts to decline and does not return to the pre-industrial level for over thousand years after atmospheric CO2 is restored to the pre-industrial concentration. The...

Oldupai Gorge is located within the Ngorongoro Conservation Area, a UNESCO World Heritage Site in northern Tanzania along the western margin of the East African Rift System. Oldupai’s sedimentary record exhibits a complex sequence of inter-stratified lithic assemblages associated with the Early, Middle, and Later Stone Age. While diachronic technological change is perceptible, the totality of locally available rocks remained largely unchanged through time. Here, thin section petrography, Scanning Electron Microscopy-Energy Dispersive X-Ray Spectroscopy, and...
